'To ALL WHoM 1T MAY ooNcERN:

Be it known that I, JOHN F. KELLER, of Greencastle, in the county of Franklin, and Stateof Pennsylvania, have invented a new and useful Improvement in Seed Planter and `Gruano Attachments; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in soconstructingrand operating the feed-slides or feed-regulators of seed planters as to increase or diminish both the length and the width` of the feed-holes in order to feed t'irough a square or nearly square hole'instead of using a long narrow feed-hole, which is liable to clog, especially with guano; and secondly, in using peculiar sharp-edged plates for the feed-slides to cut against; and thirdly in a'peculiar arrangement of stirrer or feed-agitator. In the accompanying drawings- I vFigure 1 is a side view of Imy improved seed planter.

Figure 2 is a top View of the same, only one of the drag-bars being represented.`

Figure 3 is alongitudinal section of the machine. Y

Figure 4 is a detachedview, showing the feed-agitator in the hopper.

Figure 5 is a detached view of the-feed-slide and sharp-edged plate.

Figure 6 is a detached view of the feed-slides. I

Figure 7 is a detached view of the half-bolt.

In my improved Wheat drill theVfeed-slidesv are made in two pieces or strips, as seen' at MM', g'. 6. These two strips are so arranged as to be operated either separately'or both together, as will besoon explained. When both are'operated together or as one slide, a large square feed-hole is opened, as seen at N, g. -but in ease slow feeding is desired then one of the strips; is left shut while the other half is more or less opened. Thus, one-fourth of the larger hole may be opened vand yet have a square hole, which is less liable to clogthan a long narrow hole, especially with guano lwhen a little damp; The motion of these two pieces of the feed-slide is produced as follows: The lever YO, fig. 2, is bolted to the strip M' so as to operate the same in the usual manner, while the strip M may be connected or disconnected 'with this lever at pleasure. The leverO is ycast with a half-bolt to t into the `half-hole in the strip M; and then, by using a removable half-bolt, P, iig. 7,'the Astrip Ml` may be locked to the' lever O or released 1t-pleasure. Thus either or both halves of the feed-slide maybe used. The feed-slides M M are cast with sharp edges working against the sharp edges of plate B, fig.v 5, in orderV to out clean and prevent clogging. My improved feed-agitator is best seen-in iig. 4'. The bar S carries several fingers, T, the tips of which pass down into the holes in the bottom of the hopper, so as to insure the clearing of these holes. The bar S and fingers are moved vto the right` and left in the usual manner by means of4 a. crank-lever, U, `and connecting-bar, V, which is attached'to the arm W upoh the bar S, as seen in'g. 2. v

Other features shown in' vthe above drawing are not fully described, as many of lthem are covered by patents already granted to me, and others are covered Yby applications for separatepatents which I now desire to obtain, which .applications are filed herewth.-

Having thus fully described my invention, `what I'claim, and desire to secure by Letters Patent of `the United States, iso.

1. E nlarging and diminishing both the length and the width of the feed-holes of lseed planters l in order to prevent clogging'and secure uniformity of discharge, whether slow orfast, substantially as set forth.

2. I cluirn'the arrangement and combination of the two pieces M and M of the feed-slide, substantially inthe manner and for the purpose described. u y

3. I claim the sharp-edged plates R, iig. 5, in -combination 'with thesharp edgesof the slides M M', substantially as set-forth. A

4. I also claim the use of the half-bolt, fig. 7, for locking the strip M to the lever O, substantially as set forth.
